Volly are sturdy, four-legged mammals that live on lush mountaintops, peacefully grazing on grass, flowers, and small mushrooms. Centuries ago, volly were almost entirely domesticated and bred for their restorative tears; over time, however, the human race built up a resistance to the healing effects offered by volly tears. Eventually, the last domesticated volly were released back into the wild, where they seemingly all migrated to the highest altitudes to live in isolation among small familial groups. It is generally believed that the volly have evolved over time to retain their natural healing abilities, but only for use on other volly and not for the benefit of other species.
